I recently had a ticket logged for my weewx driver that made me go on quite the long search for clarity. As part of that I opened a ticket with weatherflow since their documentation linked on this forum for the API (hosted on github I think) doesn’t match Quick Start . In that ticket they referenced the apiddocs site as the correct source of truth.
Not sure how to request the administrators of the forum to update those links? Thoughts???
Second, part of what I’m working through is a pretty big discrepancy between rain readings and nearby stations for one of the users. He’s seeing 2x - 5x the amount of rain reported from his as other nearby non-tempest stations. I’ve read about the need to calibrate and avoid vibrations, he’s going to look into that but I’m curious about a few other things… To be clear, I use the websocket API and my driver is at GitHub - livysdad27/tempestWS: Weatherflow Tempest WebSocket Driver if you want to take a gander.
What is the real difference between obs_st (rain accumulation in mm over last 60 seconds) and obs_st (nearcast rain). Is the second just an adjusted version of 12 (accumulation over last 60 seconds) or is it a daily counter or???
Has anyone ever tested the rest api vs websocket to see if they have the same obs definitions???
That’s helpful. I’m trying however to find the definition of the websocket obs_st definition for “Nearcast Rain Accumulation”. I want to validate that it’s returning “since last observation” in the same way that field 12 is. I may just open another ticket to double check.
I can not help with your detail specific question. Nearcast rain does not work for my area so I never used it. This post is similar and links to some information regarding Nearcast rain that might help understand slightly
Wow it is hard to navigate the newly reorganized pages…
GettingStarted => Quick Start => Observation and Event Definitions
This gets you to the Tempest Observations collected from midnight to midnight in the station’s local timezone. Denoted in API responses with type obs_st_ext …
12 = rain during reporting interval
19 = nearcast rain during reporting interval
17 = the reporting interval
18 = rain since midnight
20 = nearcast rain since midnight
(and I'd expect daylight savings transition days to be a mess here)
The next block of examples are Tempest Daily Observations collected from midnight to midnight in the station’s local timezone. Denoted in API responses with type obs_st_ext
